/**
 * Mob file compaction chore in a generational non-batch mode test. 1. Uses default (non-batch) mode
 * for regular MOB compaction, sets generational mode ON 2. Disables periodic MOB compactions, sets
 * minimum age to archive to 10 sec 3. Creates MOB table with 20 regions 4. Loads MOB data
 * (randomized keys, 1000 rows), flushes data. 5. Repeats 4. two more times 6. Verifies that we have
 * 20 *3 = 60 mob files (equals to number of regions x 3) 7. Runs major MOB compaction. 8. Verifies
 * that number of MOB files in a mob directory is 20 x4 = 80 9. Waits for a period of time larger
 * than minimum age to archive 10. Runs Mob cleaner chore 11 Verifies that number of MOB files in a
 * mob directory is 20. 12 Runs scanner and checks all 3 * 1000 rows.
